A steamer, A kadai.
I used my electric rice cooker, it has a steamer attachment.
1/2 Cup Cream of Rice
2 to 3 tsps oil
1/2 tsp of mustard seeds
2 Green Chillies (slit)
1 Red Chillies
About a handful of coconut, cut in tooth shaped pieces
curry leaves, two strands
1 tsp hing
1 and 1/2 tsp of salt (Depends on your taste)
1/2 tsp of Black pepper (Broken in pieces but not finely ground To acheive this you can do it in a mortar and pestle, incase you dont have one, don't fret, get a nice stone, one which will fit in the palm of you hand. Wrap the peppers in a towel and break them with the stone.)

Method
-> a kadai, add oil
->add mustard seeds once the oil is hot
->When the seeds start to sputter, add the Green Chillies, Red Chillies, Black Pepper, Coconut and Curry leaves annd hing,
-> fry for a little time and then add about 1 cup of water
-> Once the water starts to boil, switch the stove off and add the cream of rice slowly so as not form lumps, and then add salt.
